DOUBLE-LOOP BUCKLE.

PECIFICATION forming part of Letters Patent No. 385,618, dated July 3, 1888.

Serial No. 206,571. (No model.)

To LZZ whom it may concern: 1

Beit known that I, JOHN C. HAeKnrr, of Belleville, in the county ofSt. Clair and State of Illinois, have invented a certain new and useful Improvement in Detaching Double- Loop Buckles, of which the follewingis a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in which- Figure I is a perspective view of the buckle when used as a trace attacher, detaeher, and adjuster, with a detail of the haine-tug shown in dotted lines, to which tug it may be riveted, the rivets passing through the holes provided in the ends of the buckles. Fig. Il is a back view of the buckle and shows the short retention-strap which holds the swinging bail ofthe bucklcin its bearing. Fig. III is a see tion taken on line III III, Fig. II, and shows the pivot-arm of the buckle-bail llattencd behind to secure for it a lockingscat on the retention-strap when the buckle is closed. Fig. IV is a frontview ofthe buckle when used as a back-band attacher, detacher, and adjuster. It also shows means for the attachment and adjustment of the billet that secures the bellyband and the attachment-lugs, through which, when used in this capacity, the buckle is riv eted to the trace or tug-strap of the harness. Fig. V is a detail of one ofthe shafts, showing also the buckle secured thereto in its capacity as a brcechiug attacher, detacher, and adjuster; and Fig. VI is a section taken on line VI VI, Fig. V, and shows the means of securing the buckle t0 the shafts.

rlhis invention relates to devices for facilitaiing the attachment, detachment, and adjustinent of the associate parts of a set of harness together and to the shafts with which it is connected; and the invention consists in features ofnovel ty hereinafter fully described, an( pointed out in the claims.

Referring to the drawings, in which similar figures of reference indicate like parts in all the views, 1 represents the strap ef my coinbination device.

2 is the front loop; 3, the slot in the strap beneath said loop; 4, the rear loop, and 5 the slot in the strap beneath said loop.

Gis the swinging bueklebail; 7, its pivotarm, 8, the tongue of the buckle; 9, the loophandle above said tongue, and l() the slotted seat for said tongue in said strap. V

11 is the recess er corrugation in the strap in which the pivot-arm ofthe buckle-bail has its bearing; 1.2, the short retentioustrap that locks the said hail in ils bearing.

13 are the three-sided projecting lugs at the back of the strap that fence in the ends of the retention-strap,i and 14c are extensiontongues at the outer ends of said lugs, which are bent down on the retention-strap to leek it in its seat and rc-enforce its retention of the bucklebail in its bearings.

l5 are the countersunk holes in the ends of thc strap l, by which to secure it by rivets relatively either to the haine-tug 1G or the trace 17 when the buckle is used as a trace attacher, detacher, and adjuster', (sec Fig. L) except when it is preferred to make the initial attachment by the same buckle that secures the corresponding part, as hereinafter described. When used as a back and belly band attacher, detacher, and adjuster, (see Fig. IV,) the said holes may be dispensed with and perforated lugs 19 be cast integral on the sides of the strap or otherwise suitably secured there, as shown in Fig. lV. These perforated lugs provide the means for securing the buckle to the tugstrap or trace with which it is desired to connect the back and belly bands. Rivets 20 pass through said perforations and through said strap or trace, to which they provide a riveted attachment of the buckle; also, when used in this capacity, a side loop, 2l, is provided, which may be cast integral with the strap l. This side loop provides the means for the brcechiug attachment when the device is used on double harness.

When used as a brcechiug attacher, detacher, and adjuster for single harness, (see Figs. V and Vl,) exactly the saine forni of met-al loop-buckle is used as for the trace attachment, except that the sides of the strap are provided with bevelanged edges 22, that engage snugly with the bevel edge ef the shaft, to which it is rmly secured by the screws 23, that pass through the countersunk holes aforesaid at the ends of the buckle-strap and are screwseated in the shaft. (See Fig. VI.)

This application ofthe attachment avoids the objectionable necessity ofW rapping the breech- ,iug or holdback strap around the shaft.

I have described the buckle-loop strap as riveted relatively to the haine-tug or trace, according as it is preferred to first permanently attach it to the 011e or the other; but I do not confine myself to that means of initial permanent attachment, for I sometimes prefer to dispense with theriveting and utilize the same locking-buckle for the attach meut of its loopstrap to both the hametug and trace,which it couples together, in which case both the haine-tug an d trace have buckleholes punched iu them, so as to be able to adjust both of them to the length required, as will be de scribed in the attachingoperation of the device.

The pivot-arm of the bucklevbail is provided with a flatside, 2i, that, when the buckle is operative, its against the face of the short retentioirstrap I2, (that holds said pivot-arm in its beariug,) and thus locks the buckle and prevents its tongue from jerking out from its seat.

I will now describe the operation of my invention and refer to the facilities that it affords for the attachment, detachment, and adj ustment of the several parts of the harness that it unites-viz., as a trace attachment, a buck-strap and belly-band attachment, and a breeching attachment.

If not riveted to said hame-tug, as previously described, the short hame-tug strap is passed through the rear loop, then under the hinged buckle-bail, and lastly through the front loop, and adjusted to the length desired, with care that one of the punched holes in the strap is located opposite the perforation or slot in the metal strap that seats the tongue of the buckle. The perforated end of the trace is then passed through the front loop, then under the hinged buckle-bail,and lastly through the rear loop, adjusting it longitudinally to the length of trace required, having a care at the same time that the buckle-holes in the trace shall correspond with those in the tug. The hinged bucklebail is then turned down and its tongue made to engage iu the corresponding holes in both trace and haine-tug, and the flat face on the pivot arm of the hinged buckle-bail then, engaging against the face of the retention-strap, locks the said buckle in ils seat. \Vhen it is preferred to make the initial attachment (that is, the attachment of the first member to the coupling) by riveting the met-al looped strap thereto, then the second part in the union (which may be, as just described, the trace) is alone required to be passed through the loops and under the hinged buckle-bail; but even in that continL gcncy the tongue of said buckle-bail also passes lhrough a perforation in said first part and re-euforces the attachment of the coupling.

Second, in its use as a back-baud billet and belly-band attachment, the perforated side lugs of the metal loop-strap having been riveted to the trace or tug, the end Vof the bit let (that buckles to the belly-band, which is provided with a series of punched holes, so as to adjust the belly-baud to the size of the horse that Wears the harness) is first passed through the rear loop, then` under or through the hinged buckle-bail and over the corrugated bridge that rides above the bearing ofthe bail-buckle, and lastly through the front loop until the one desired of its buckle-holes corresponds with the perforate seat of the buckletongue inthe metal loop buckle-strap. The tug end of the back-band (Which also has a series of holes punched in it to adjust it to the length required) is then passed through the loops and hinged bucklebail in the reverse direction to that just described of the billet until the desired length of insertion is attained to adjust the length of the back-band to the size of the horse that Wears it and to adjust the buckle-holes to those of the billet. The hinged buckle-bail is then closed down andthe short buckletongue from its front arm is seated in the holes of both the back-band and billet, and the flattened face of the pivot-arm simultaneously falls into coincidence with the face of the retention-strap, and so locks the hinged bailbucklein its seat, although it is again, when desired, unlocked with sufficient ease when projected from its dat bearing to its rock-bearing against the re` tention-strap.

Third, in its capacity as a breeching attachment, the metallic straps as thus used (see Figs. V and VI) are provided with bevel side edges that cling closely to the bevel inside of the shafts, to which they are secured by screws. The attachment ends of said breeching-straps, that have a series of holes punched in them,pass around and through the front loop, then through the hinged bailbuckle, over the corrugated bridge that rises above the bearing of the bailbuckle, and lastly through the rear loop, and are drawn through to adjust the holdback to the required length. 'Ihe hinged bail-buckle is then pressed down, and its tongue engages in one oi' the holes in the strap, and is there locked, as heretofore described.

The metal strap may be made of malleable cast-iron, brass, silver, or any other suitable metal.

I claim as my invention- 1. In an attachment device for harness, the metal strap, a loop at each cud of said strap, and the intermediate buckle between said loops, substantially as and for the purpose set forth.

2. In an attachment device for harness, the metal strap, a loop at each end of said strap, the swinging bail hinged between said loops, and the buckletongue on said bail, substantially as and for the purpose set forth.
